仅在模块中加载 Yii Bootstrap

我尝试仅在管理模块中加载 Yii Bootstrap 扩展，但它不起作用。我假设我需要预加载它或以某种方式启动它......谢谢！

    class AdminModule extends CWebModule
    {
        public function init()
        {
            // import the module-level models and components
            $this->setImport(array(
                'admin.models.*',
                'admin.components.*',
                'ext.bootstrap.components.Bootstrap',
            ));
        }

        public function beforeControllerAction($controller, $action)
        {
            if(parent::beforeControllerAction($controller, $action))
            {
                         $this->layout = 'admin';                
                         return true;
            }
            else
                return false;
        }
    }

有 4 种不同的方法可以做到这一点：

1. 将配置添加到应用程序的配置中（受保护/配置/main.php):

   'modules'=>array(
       'admin'=>array(
           'preload'=>array('bootstrap'),
           'components'=>array(
               'bootstrap'=>array(
                   'class'=>'ext.bootstrap.components.Bootstrap'
           )
       ),
   // ... other modules ...
   )    
   

2. 将其预加载到init :

   public function init()
   {
       // import the module-level models and components
       $this->setImport(array(
           'admin.models.*',
           'admin.components.*',
           // 'ext.bootstrap.components.Bootstrap', // this will go to app config for components
       ));
       Yii::app()->getComponent('bootstrap');// this does the loading
   }
   

3. 预加载于init其他方式：

   public function init()
   {
       // import the module-level models and components
       $this->setImport(array(
           'admin.models.*',
           'admin.components.*',
       ));
   
       $this->configure(array(
               'components'=>array(
                   'bootstrap'=>array(
                       'class'=>'ext.bootstrap.components.Bootstrap'
                   )
               )
       ));
       $this->getComponent('bootstrap');
   }
   

4. 预加载于init还有另一种方式：

   public function init()
   {
       // import the module-level models and components
       $this->setImport(array(
           'admin.models.*',
           'admin.components.*',
       ));
   
       $this->configure(array(
               'preload'=>array('bootstrap'),
               'components'=>array(
                   'bootstrap'=>array(
                       'class'=>'ext.bootstrap.components.Bootstrap'
                   )
               )
       ));
       $this->preloadComponents();
   }
